KOH is clear

Iff you look at the image 83262 It is the collection red topped tube. I dropped a small piece of the specimen and added KOH .3 mls of KOH. At first the KOH turns Orange yellow then that brown color. I am finding this true for a lot of different species of fungi. Some have no affect on the KOH leaving it clear or tepid but some like Galerina turn KOH Black. I noticed this last year with a Leccinum turning the KOH a brilliant Red. Iv also notice the KOH turning a color but having very little affect on the small piece I put in the sample container.

I don’t quite see
